【通信录操作】
使用ContentResolver对通信录中的数据进行添加、删除、修改和查询操作：
加入读写联系人信息的权限
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
  1 加入读取联系人信息的权限
  2 <uses-permission android:name="android.permission.READ_CONTACTS"/>
  3 
  4 content://com.android.contacts/contacts 操作的数据是联系人信息Uri
  5 content://com.android.contacts/data/phones 联系人电话Uri
  6 content://com.android.contacts/data/emails 联系人Email Uri
  7 
  8 读取联系人信息
  9 Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,  
 10     null, null, null, null);  
 11   while (cursor.moveToNext()) {  
 12    String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));  
 13    String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));  
 14    
 15    Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,  
 16         null,  
 17         ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,  
 18         null, null);  
 19     while (phones.moveToNext()) {  
 20      String phoneNumber = phones.getString(phones.getColumnIndex(  
 21          ContactsContract.CommonDataKinds.Phone.NUMBER));  
 22      Log.i("RongActivity", "phoneNumber="+phoneNumber);
 23     }  
 24     phones.close();  
 25    
 26     Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,  
 27        null,  
 28        ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,  
 29        null, null);  
 30        while (emails.moveToNext()) {  
 31         // This would allow you get several email addresses  
 32         String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
 33         Log.i("RongActivity", "emailAddress="+ emailAddress);
 34        }  
 35        emails.close();  
 36   }  
 37   cursor.close();

 40 方法一：
 41     /**
 42      * 首先向RawContacts.CONTENT_URI执行一个空值插入，目的是获取系统返回的rawContactId 
 43      * 这时后面插入data表的依据，只有执行空值插入，才能使插入的联系人在通讯录里面可见
 44      */
 45     public void testInsert() {
 46         ContentValues values = new ContentValues();
 47         //首先向RawContacts.CONTENT_URI执行一个空值插入，目的是获取系统返回的rawContactId 
 48         Uri rawContactUri = this.getContext().getContentResolver().insert(RawContacts.CONTENT_URI, values);
